yes

you should remember divide first before add or subtract start on the left side and do 12 divided by 4 first. what do you get ?
anonymous
  • anonymous
3
phi
  • phi
yes, so replace \(12 \div 4\) with 3 what do you have now?
anonymous
  • anonymous
3 + 9 - 3 x 4
phi
  • phi
ok, now look for any multiply (or divide) if you find one, do it.
anonymous
  • anonymous
3 x 4 = 12
phi
  • phi
ok, so replace 3*4 with 12 what do we have now?
anonymous
  • anonymous
3 + 9 - 3 and idk what to do with the 12
phi
  • phi
you had 3+9 - 3*4 you do the multiply
anonymous
  • anonymous
i did. its 12
phi
  • phi
yes, and how do write the new expression (it has to have a 12 in it)
anonymous
  • anonymous
idk then
phi
  • phi
3+9 - 3*4 replace 3*4 with 12 (they mean the same thing)
anonymous
  • anonymous
3 + 9 - 12
phi
  • phi
ok, now with just add subtract, work left to right first do 3+9
anonymous
  • anonymous
the answer would be 0
phi
  • phi
yes
anonymous
  • anonymous
3 + 9 = 12, 12 - 12 = 0
anonymous
  • anonymous
i've got a feeling this is somehow wrong but oh well
anonymous
  • anonymous
its never been 0
phi
  • phi
if this is the question \[ 12\div 4+9-3\times 4 \] then 0 is the answer
phi
  • phi
in math, if you follow the rules carefully, you get the answer.

Let's simplify step-by-step. 12 4 +9−3x(4) =3+9+−12x Combine Like Terms: =3+9+−12x =(−12x)+(3+9) =−12x+12 Answer: =−12x+12
